Subject : 2.6.34-rc3 doesn't suspend to disk (-rc2 did) Submitter : Jiri Kosina <jkosina@suse.cz> Date : 2010-04-02 0:19 Message-ID : alpine.LNX.2.00.1004020215100.8345@pobox.suse.cz References : http://marc.info/?l=linux-kernel&m=127016758131762&w=2 This entry is being used for tracking a regression from 2.6.33. Please don't close it until the problem is fixed in the mainline.
I hit that with opensuse factory today. echo disk > /sys/power/state works fine there. The kernel is -rc2-git3 (plus other patches of course). I'll look into that later if noone beats me to it.
Created attachment 25923 [details] patch for the issue I'm not sure whether the second paragraph in the changelog holds. For me it works.
OK, I assume you have tested it both with and without CONFIG_DEBUG_BLOCK_EXT_DEVT. I guess it should be pushed to Linus soon. I wonder which change broke it, though. Handled-By : Jiri Slaby <jslaby@suse.cz> Patch : https://bugzilla.kernel.org/attachment.cgi?id=25923
